Abstract

A coding apparatus which codes moving image signals into block units, is configured from a signal processing element which performs motion compensation for moving image signals for over a plural number of frames or fields and codes inter-image signals, and a transfer element which recombines coded information for each block coded by said processing element, into macroblock units which are a plural number of block units of each type of coded information, and transfers them. In addition, a decoding apparatus for moving image signals which have been coded in block units is configured from a detector element which detects transfer code errors for each type of coded information, and a processing element which performs motion compensation and inter-image processing of the coded information using only correct frames which do not include transfer code errors, and without using frames which have transfer code errors, by changing a method of inter-frame processing for motion compensation in accordance with the transfer coding errors in the coded information which has been detected for each type.
